Abstract
The present invention relates to a method of processing video signals comprised of gamma correcting pixel data of a first signal, gamma correcting pixel data of a second signal, adding the gamma corrected first and second signals to form a sum signal, dividing the sum signal by a factor to form a processed signal, and reverse gamma correcting the processed signal, whereby merged pixel data is produced for generation of a display.
Claims17
A method of processing video signals comprising:
- (a) gamma correcting pixel data of a first signal,
- (b) gamma correcting pixel data of a second signal,
- (c) adding the gamma corrected first and second signals to form a sum signal,
- (d) dividing the sum signal by a factor to form a processed signal, and
- (e) reverse gamma correcting the processed signal,
- whereby merged pixel data is produced for generation of a display.

A method of processing digital video signals comprising:
- (a) separately gamma correcting pixel data of individual pixels of plural video signals,
- (b) adding the gamma corrected pixel data to form a sum signal for each pixel to be displayed,
- (c) dividing each of the sum signals by a factor, to form processed signals, and
- (d) reverse gamma correcting each of the processed signals,
- whereby merged pixel data is produced for generation of a display.
